Detailed Description

Implementation using Random.h default random engine.

This engine is also used by other engines for seeding.

Example Use: Using Default Engine with RandomWalk

Markov::Model<char> model;
Model.import("model.mdl");
char* res = new char[11];
Markov::Random::DefaultRandomEngine randomEngine;
for (int i = 0; i < 10; i++) {
    this->RandomWalk(&randomEngine, 5, 10, res); 
    std::cout << res << "\n";
 }

Example Use: Generating a random number with Marsaglia Engine

Markov::Random::DefaultRandomEngine de;
std::cout << de.random();
